TOTALIZED DATA COMPARISON SYSTEM OF ELECTRONIC REGISTER

摘要

PURPOSE:To make sale activity effective by eliminating the need for manual rate calculation by automatically calculating the rate of previous totalized date, which correspond to current totalized data, to the current totalized data in checking and reckoning and then by printing the rate data together with the current totalized data. CONSTITUTION:The CPU 12 is connected to I/D port 9 of ECR, and CPU 21 processes the variaus impormation by a fixed method, these imformation are inputted from key input part 1, print part 11, display part 10, and input part 1. connecting with data bus line DB, address bus line AB and control bus line CB connected to I/O port 9 and CPU 12 of this ECR, totalizing memory I having flag F1 stored with current input totalized data and totalizing memory II having flag F2 stored with previous input totalized data are provided. Then when indication information for a check and totalization is inputted from input part 1, the rate of the previous totalized data to the current totalized data is calculated by CPU 12 and it is made possible to print the rate data and current totalized data together by print part 11.
